The Mysteries of Slime Mold

Originally I'd mistaken slime mold for a form of fungus—and indeed scientists classified it as a fungus for a long time until quite
recently—when in fact slime mold comprises its own kingdom of life, unrelated to fungi, plants or animals. They've been described as "sacks of
amoebas" that, despite having no nerve cells, demonstrate a rudimentary intelligence, with the ability to seek out food sources and remember
locations; even more amazingly, behaviors and memories are shared by an entire colony. While some are kind of disgusting in appearance (one
variety is even called "dog vomit"), many of them have a beauty all their own. Hover
